Now the wheel is stuck in the occulting position so I paused the program so I can try to fix this ongoing stall problem. Sun Jan 2 18:10:35 GMT 2000 PICS End Patrol **MKIV PROBLEM**: Sun Jan 2 18:13:10 GMT 2000 No xanim animations, I checked the MkIV data directory and there are no .gif files there, and there are some files which look oddly named, like 100d00218_07.mk4.ba, I'm just guessing when I say that maybe that file name should start with 00 instead of 100. But data are going to that directory so I think we're OK. LOW-L COMMENT: Sun Jan 2 18:29:38 GMT 2000 Tape L00655 had 80 files on it so I replaced it with L00657 in drive #1 after I cleaned that drive, data going to L00656 in drive #0 now. This PC also showed the date as 1/1980 and was 9 minutes fast, but that didn't affect the lowl program screen display. I set the date correctly for the PC and the year in the ctconfig file (not sure if this is still needed). **GONG PROBLEM**: Sun Jan 2 18:37:21 GMT 2000 They had a problem with the instruments shortly after the year change. I don't see any solar image although the program is running and there are no error messages. The console took a long time to clear previous error message and "update display" after I clicked on those requesters. GONG people said they are still working on some problems. **MLSO PROBLEM**: Sun Jan 2 18:45:41 GMT 2000 Network connection is very slow.

The date change was handled correctly by that PC, year is shown as 2000, and abbreviated year is 00 for file creation dates.

I guess the motor is just worn out and doesn't have the starting torque is used to have. I'll replace it with the spare motor and see if the wheel stalls. Everything else in the system seems to be within tolerances. WEATHER COMMENT: Sun Jan 2 21:42:07 GMT 2000 Orographic clouds are passing over. COMMENT: Sun Jan 2 21:42:55 GMT 2000 Unfortunaately I must have bumped the spar off the sun a while back when I was working on the occulting wheel, I repointed and reset the guider now.

It worked well for a few moves then I noticed a Timeout message and it appeared that the wheel stalled so I stopped Patrol but then the wheel moved. So I tried using the mouse to move the wheel and it worked without fail, then I tried Video and it seemed to work but there were Optics:Timeouts, then I tried Patrol again. I think the Timeouts are at least partially due to the Objective Wheel card being used for the Occulting wheel, I can see the fields for the Objective wheel turn red and yellow during Patrol, is this wheel used during Patrol? The LEDs show that the occulting wheel is moving, and it looks normal between H-alpha disk to H-alpha limb as the occulter is rotated into place, but the GUI fields look funny when rotating back to the Clear position (for H-alpha disk images), the various fields light up out of order and some of them light multiple times during the move, and the Dark field ends up lit. It's cloudy, but I opened the dome to see if the wheel is making it to the Clear position, but this time the Clear field was white (lit) and the disk image was there, so it worked correctly, very weird, then it kept working correctly after that, I don't understand why. The only thing that changed is that the spar is pointed at the sun now, yet the occulting wheel is moving to the correct position for the limb images and it wasn't before, the "Bit 1" LED is lit for a disk image, but the "Bit 0" LED was lit before. Maybe I didn't align the home limit switch correctly. **PICS PROBLEM**: Sun Jan 2 23:32:47 GMT 2000 OK, now the Bit 0 LED is lit for the disk image, wrong LED, I'll check the home switch again. Sun Jan 2 23:35:43 GMT 2000 PICS End Patrol **PICS PROBLEM**: Sun Jan 2 23:40:43 GMT 2000 I think the home switch is aligned correctly you can see the Bit LED light then the Home LED, then the Home LED goes out, then the Bit LED goes out, this is all correct. I can use the mouse to repeatedly go back and forth from Occult to Clear (stations) without a problem, it seems there is only a problem when this is done from the Patrol program. I tried it in the Video program (using the mouse to move the wheel) and it worked without fail. So currently I haven't seen the wheel stall with the spare motor installed but sometimes the wheel goes to the Dark position when Patrol is running and should be sending it to the Clear position, this may be where the wheel ends up if there is a Timeout (?)
